There's a peculiar thing happening in my launchpad. On opening it up anytime in general, all the folders show no icons in them but blank squares drawn using dashed lines, the icons don't come back even if I wait a while. If I go inside a folder, the icons are there. If I close launchpad right away and reopen it again immediately, the icons are there. I am almost certain this started after upgrading to Sierra.
Of course, if I do
killall Dock, it works but only until I reboot/logout. The other thing advised to do in this case is to remove the
.db files in
~/Library/Application Support/Dock but that location is empty on my machine.
This isn't at all a showstopper, but is certainly very odd, and I would like to do something about it, if there's something reasonable that can be done about it, as a long-term/permanent fix.
